Haircut traditionally associated with American whitetrash, wrestlers, middle of the road american cockrock bands, and in general the eras of the late 70's through to the 80's.

However the mullet is currently making a resurgence in metrosexual males from the Welsh valleys.
Often associated with scarily clone-like steroid using, fake tan covered, pink t-shirt wearing posers who love themselves and spend far more time in the gym and hairdressers than any straight male ever should.
Affectionately known locally as "Spice Boys" - known more generally as "twats"
Apparently they are unaware that the mullet has not been considered cool (outside of Arkansas that is) for over 20 years

"check out the mullets on those spice boys over there - its like they're in fucking uniform man!"

"spice boys? - is that what you call them round here? - back home we just call them Twats and be done with it"

Business in the front, party in the back. Mullets started in the late 60s early 70s. By the eighties, everyone had them, absolutely everyone (who was white, blacks had jerry curls or high top fades.) Then it all came to an end when Kurt Cobain called Brett Michaels girly-looking. Billy Ray Cyrus had one, but that was like the drunk uncle at a 10 year old's birthday party. Now it's only worn by hockey and soccer players.

The term mullet was invented and 1st used in pop culture by the Beastie Boys. Who knew?

Any haircut that is short in the front, long in the back, and identified with certain regional and socio-economic norms. Usually worn by males, though not exclusively. In the USA, it is usually associated with lower education and/or income males, and often considered a sign of white trash, trailer trash or redneck status. However, in Canada, the mullet is simply known as the hockey haircut, and is a practical choice for those who play Canada's national sport because it allows the player to wear a helmet and keep his long hair.
